Description

Die Erfindung betrifft eine Intumeszenz-Brandschutzvorrichtung zum Verschließen von Durchbrüchen in Wänden oder Decken sowie einen Durchbruch in einer Wand oder einer Decke, mit einer Innenwand und einer an der Innenwand anliegenden Intumeszenz-Brandschutzvorrichtung.The invention relates to an intumescent fire protection device for closing openings in walls or ceilings as well as an opening in a wall or a ceiling, with an inner wall and an intumescent fire protection device resting on the inner wall.

Brandschutzwände und -decken unterliegen besonderen Vorschriften in Hinsicht auf ihre Rauchdurchlässigkeit und Feuerbeständigkeit. Jedoch müssen auch durch Brandschutzwände Leitungen, Rohre oder andere Objekte hindurchgeführt werden. Hierzu werden Durchbrüche in die Brandschutzwand eingebracht, um die Objekte durchzuführen. Durch diese Durchbrüche werden allerdings die Eigenschaften der Wand oder Decke als Brandschutzwand beeinträchtigt, sodass die Durchbrüche wieder verschlossen werden müssen.Fire protection walls and ceilings are subject to special regulations with regard to their smoke permeability and fire resistance. However, cables, pipes or other objects must also be passed through fire protection walls. For this purpose, openings are made in the fire protection wall in order to pass through the objects. However, these openings impair the properties of the wall or ceiling as a fire protection wall, so that the openings have to be closed again.

Hierzu werden Brandschutzvorrichtungen verwendet, die ein intumeszierendes Material aufweisen und die die brennbaren Leitungen im Durchbruch umgeben. Im Falle eines Brandes brennt das Material der Leitung weg, wodurch ein unerwünschter Hohlraum entsteht. Dieser Hohlraum wird durch das Aufblähen des intumeszierenden Materials der Brandschutzvorrichtung wieder rauch- und feuerfest verschlossen. Eine solche Vorrichtung ist aus Dokument EP 0 506 497 A1 bekannt.For this purpose, fire protection devices are used which have an intumescent material and which surround the combustible lines in the opening. In the event of a fire, the pipe material burns away, creating an undesirable cavity. This cavity is closed again in a smoke and fire-proof manner by the expansion of the intumescent material of the fire protection device. Such a device is from document EP 0 506 497 A1 known.

Die verwendeten intumeszierenden Materialien benötigen jedoch meist eine Temperatur von wenigstens ca. 200 °C, damit die Intumeszenz, also das Aufblähen des intumeszierenden Materials, in Gang gesetzt wird.The intumescent materials used, however, usually require a temperature of at least approx. 200 ° C. so that the intumescence, that is to say the inflation of the intumescent material, is set in motion.

In der Regel haben die Leitungen jedoch einen Schmelzpunkt unter 200 °C, sodass die Leitungen wegbrennen oder schmelzen, noch bevor die Intumeszenz einsetzt. Die Hohlräume entstehen also, bevor die Intumeszenz in Gang gesetzt wird, und müssen dann möglichst schnell geschlossen werden.As a rule, however, the lines have a melting point below 200 ° C, so that the lines burn or melt before the intumescence starts. The cavities are created before the intumescence is set in motion and must then be closed as quickly as possible.

Problematischerweise stehen bei üblichen Brandschutzvorrichtungen lediglich die Stirnseiten der Brandschutzvorrichtung in direktem Kontakt mit dem Feuer, wodurch lediglich an der Stirnseite die Intumeszenz rasch in Gang gesetzt wird. Durch das Aufblähen an der Stirnseite werden jedoch die weiteren Bereiche der Brandschutzvorrichtung gegenüber dem Feuer isoliert, sodass in diesen weiteren Bereichen die Intumeszenz viel später einsetzt.The problem with conventional fire protection devices is that only the end faces of the fire protection device are in direct contact with the fire, as a result of which the intumescence is quickly set in motion only on the end face. However, the expansion on the front side isolates the other areas of the fire protection device from the fire, so that intumescence begins much later in these other areas.

Es ist somit Aufgabe der Erfindung, eine Intumeszenz-Brandschutzvorrichtung zum Verschließen von Durchbrüchen in Wänden oder Decken bereitzustellen, die die Hohlräume, die durch Abbrand der Leitungen entstehen, schnell und vollständig verschließen.It is therefore the object of the invention to provide an intumescent fire protection device for closing openings in walls or ceilings, which quickly and completely closes the cavities that are created by the burning of the lines.

Die Aufgabe wird gelöst durch eine Intumeszenz-Brandschutzvorrichtung zum Verschließen von Durchbrüchen in Wänden oder Decken, mit mehreren plattenförmigen Trägern, die auf zumindest einer Seite mit einer intumeszierenden Beschichtung versehen sind, wobei die Träger in einem Überlappbereich einander teilweise überlappend so aneinander befestigt sind, dass ein Band oder Ring erhalten ist, dessen Länge größer ist als die Länge eines einzelnen Trägers, dadurch gekennzeichnet, dass die Träger mittels einer Klammer und/oder durch eine Naht aneinander befestigt sind.The object is achieved by an intumescent fire protection device for closing openings in walls or ceilings, with several plate-shaped carriers which are provided with an intumescent coating on at least one side, the carriers being fastened to one another in an overlapping area, partially overlapping one another, so that a band or ring is obtained, the length of which is greater than the length of a single carrier, characterized in that the carriers are attached to one another by means of a clip and / or by a seam.

Hierbei sollen unter Durchbrüchen in Wänden oder Decken auch solche Durchbrüche umfasst werden, die zur Durchführung von Rohrleitungen, insbesondere Abwasserrohren, im Untergrund dienen.Here, openings in walls or ceilings are also intended to include those openings that are used to lead through pipelines, in particular sewer pipes, underground.

Dadurch, dass die Brandschutzvorrichtung aus mehreren überlappenden Trägern zusammengesetzt ist, ist es möglich, dass sich die Träger im Überlappbereich voneinander entfernen. Dadurch entstehen innerhalb der Brandschutzvorrichtung Kanäle für heißen Rauch und Feuer, sodass die Oberfläche vergrößert wird, die Rauch oder Feuer ausgesetzt ist. Durch diese im Vergleich zu starren, ringförmigen Brandschutzvorrichtungen größere Oberfläche kann Feuer oder heißer Rauch schneller zu einer Erwärmung der gesamten Brandschutzvorrichtung führen. Somit wird die Temperatur, bei der die Intumeszenz einsetzt, rasch erreicht. Auf diese Weise können im Hohlraum entstandene Durchbrüche schneller verschlossen werden.Because the fire protection device is composed of several overlapping beams, it is possible for the beams to move away from one another in the overlapping area. This creates channels for hot smoke and fire within the fire protection device, thereby increasing the surface area that is exposed to smoke or fire. As a result of this larger surface compared to rigid, ring-shaped fire protection devices, fire or hot smoke can lead to the entire fire protection device heating up more quickly. The temperature at which the intumescence begins is thus quickly reached. In this way, openings that have arisen in the cavity can be closed more quickly.

Vorzugsweise sind die Träger an ihrem hinteren Längsende mit dem jeweils vorhergehenden Träger verbunden, und die Verbindung der Träger mit dem jeweils nachfolgenden Träger unterteilt die Träger derart in zwei Abschnitte, dass das vordere Längsende der Träger unbefestigt ist. In anderen Worten sind die Träger in Längsrichtung nur an einer Stelle aneinander befestigt. Dabei sind die Angaben "vorhergehend", "nachfolgend", "Längsende", etc. in Bezug auf die Längserstreckung bzw. -richtung des Bandes oder des Ringes gewählt, wenn das Band am Boden ausgebreitet bzw. der Ring abgewickelt ist. Diese Angaben dienen lediglich zur Vereinfachung der Beschreibung, denn selbstverständlich hat ein geschlossenes Band oder ein Ring keine Längsenden oder eine Reihenfolge bzw. Richtung.The carriers are preferably connected at their rear longitudinal end to the respective preceding carrier, and the connection of the carrier to the each subsequent carrier divides the carrier into two sections in such a way that the front longitudinal end of the carrier is unattached. In other words, the carriers are attached to one another at only one point in the longitudinal direction. The indications "previous", "following", "longitudinal end", etc. are selected in relation to the longitudinal extension or direction of the band or the ring when the band is spread out on the ground or the ring is unwound. This information is only used to simplify the description, because of course a closed band or ring has no longitudinal ends or a sequence or direction.

Dadurch, dass die Träger an ihrem hinteren Längsende mit dem jeweils vorhergehenden Träger verbunden sind, ist das vordere Ende gegenüber den übrigen Trägern frei beweglich und kann sich somit in die durch den Abbrand der Leitung entstandenen Hohlräume hinein bewegen, wodurch die Oberfläche und das verschlossene Volumen der Brandschutzvorrichtung unmittelbar nach entstehen des Hohlraumes vergrößert wird.Because the carriers are connected at their rear longitudinal end to the respective preceding carrier, the front end is freely movable with respect to the other carriers and can thus move into the cavities created by the burn-off of the line, thereby creating the surface and the closed volume the fire protection device is enlarged immediately after the cavity is created.

Beispielsweise sind die Träger mittels einem Faden, vorzugsweise aus Polyamid-, Aramid-, Carbon-, Glas-, Keramik-, oder Stahlfaser, aneinander befestigt, wodurch eine kostengünstige und belastbare Verbindung zwischen den Trägern hergestellt wird.For example, the carriers are attached to one another by means of a thread, preferably made of polyamide, aramid, carbon, glass, ceramic, or steel fibers, whereby an inexpensive and resilient connection is established between the carriers.

In einer Ausführungsform der Erfindung ist die Beschichtung zumindest teilweise in einem Teil des Überlappbereiches zwischen den beiden überlappenden Trägern vorgesehen. Auf diese Weise führt ein Aufblähen der Beschichtung im Überlappbereich dazu, dass die Träger weiter voneinander weg bewegt werden, sodass ein sich selbst verstärkender Effekt erzielt wird.In one embodiment of the invention, the coating is provided at least partially in part of the overlap area between the two overlapping supports. In this way, expansion of the coating in the overlap area leads to the carriers being moved further away from one another, so that a self-reinforcing effect is achieved.

Beispielsweise weisen die Träger mitsamt der Beschichtung wenigstens einen Einschnitt auf, der sich vom vorderen Längsende aus erstreckt. Dabei erstrecken sich die Einschnitte ebenfalls im Wesentlichen in Längsrichtung, sodass die Beweglichkeit der Träger untereinander deutlich erhöht wird.For example, the carriers together with the coating have at least one incision which extends from the front longitudinal end. The incisions also extend essentially in the longitudinal direction, so that the mobility of the carriers among one another is significantly increased.

In einer Ausführungsvariante ist, wenn die Intumeszenz-Brandschutzvorrichtung ohne Belastung ausgebreitet ist, das vordere Längsende der Träger vom jeweils nachfolgenden Träger mitsamt Beschichtung beabstandet. Dabei können die Träger konkav ausgeführt sein. Auf diese Weise werden die Träger gegeneinander vorgespannt, wenn die Intumeszenz-Brandschutzvorrichtung in einem Durchbruch zwischen der Innenwand des Durchbruches und der Leitung angeordnet ist.In one embodiment variant, when the intumescent fire protection device is spread out without loading, the front longitudinal end of the carrier is from the respective subsequent carrier together with the coating spaced. The carriers can be concave. In this way, the carriers are biased against each other when the intumescent fire protection device is arranged in an opening between the inner wall of the opening and the line.

Vorzugsweise sind die Träger identisch ausgeführt, wodurch die Herstellungskosten stark gesenkt werden können.The carriers are preferably designed to be identical, as a result of which the production costs can be greatly reduced.

Beispielsweise haben die Träger eine rechteckige Grundfläche, wobei die längere Seite der rechteckigen Grundfläche in Längsrichtung des Bandes orientiert ist, wodurch auf einfache Weise ein Band oder ein Ring realisiert wird.For example, the carriers have a rectangular base area, the longer side of the rectangular base area being oriented in the longitudinal direction of the band, whereby a band or a ring can be realized in a simple manner.

In einer Ausführungsform der Erfindung sind die Träger beidseitig mit der Beschichtung versehen, wodurch eine besonders große Oberfläche der intumeszierenden Beschichtung bereitgestellt wird.In one embodiment of the invention, the carriers are provided with the coating on both sides, whereby a particularly large surface area of the intumescent coating is provided.

Vorzugsweise ist die Beschichtung zumindest im Bereich des vorderen Längsendes zwischen den überlappenden Trägern vorgesehen, sodass die Träger aufgrund der Hebelwirkung effektiv beim Aufblähen der Beschichtung voneinander entfernt werden.The coating is preferably provided at least in the region of the front longitudinal end between the overlapping carriers, so that the carriers are effectively removed from one another due to the leverage effect when the coating is expanded.

In einer Ausführungsvariante ist die Beschichtung vollflächig auf die Träger aufgebracht, wodurch die Herstellung der Brandschutzvorrichtung vereinfacht wird.In one embodiment, the coating is applied over the entire surface of the carrier, which simplifies the manufacture of the fire protection device.

In einer Ausgestaltung der Erfindung sind die Träger aus einem Gewebe oder einem Gitter, insbesondere einem Glasfasergewebe oder einem Glasfasergitter hergestellt, wodurch beständige und gleichzeitig flexible Träger ermöglicht werden.In one embodiment of the invention, the carriers are made from a fabric or a grid, in particular a glass fiber fabric or a glass fiber grid, which enables stable and at the same time flexible carriers.

Beispielsweise weist die Intumeszenz-Brandschutzvorrichtung wenigstens einen Haken auf, mit dem die Intumeszenz-Brandschutzvorrichtung an einer Wand oder Decke befestigt werden kann, wodurch keine zusätzlichen Teile für eine Vorwandmontage notwendig sind. Dabei können die Haken aus Stahl sein.For example, the intumescent fire protection device has at least one hook with which the intumescent fire protection device can be fastened to a wall or ceiling, so that no additional parts are necessary for wall mounting. The hooks can be made of steel.

Ferner wird die Aufgabe gelöst durch einen Durchbruch in einer Wand oder einer Decke, mit einer Innenwand und einer an der Innenwand anliegenden Intumeszenz-Brandschutzvorrichtung wie zuvor beschrieben, wobei die Längsenden der Träger, die im jeweiligen Überlappbereich radial innen liegen, gegenüber den im jeweiligen Überlappbereich radial außen liegenden Trägern beweglich sind. Auf diese Weise können sich die radial innen liegenden Längsenden der Träger ohne allzu großen Kraftaufwand in entstehende Hohlräume bewegen.Furthermore, the object is achieved by an opening in a wall or a ceiling, with an inner wall and an intumescent fire protection device resting against the inner wall, as described above, the longitudinal ends of the beams, which lie radially inward in the respective overlap area, are movable with respect to the carriers lying radially on the outside in the respective overlap area. In this way, the radially inner longitudinal ends of the carrier can move into cavities that are created without excessive expenditure of force.

Beispielsweise sind die Längsenden der Träger, die im jeweiligen Überlappbereich radial außen liegen, am radial innen liegenden Träger befestigt, wodurch der Bewegungsumfang der freien Längsenden der Träger maximiert wird.For example, the longitudinal ends of the carriers, which are located radially on the outside in the respective overlap area, are attached to the radially inner carrier, whereby the range of movement of the free longitudinal ends of the carriers is maximized.

Die Figuren 1 und 2 zeigen eine Intumeszenz-Brandschutzvorrichtung 10, im Folgenden nur kurz Brandschutzvorrichtung 10 genannt, mit mehreren plattenförmigen Trägern 12, die mit einer intumeszierenden Beschichtung 14 versehen sind.The Figures 1 and 2 show an intumescent fire protection device 10, hereinafter referred to as fire protection device 10 for short, with several plate-shaped supports 12 which are provided with an intumescent coating 14.

Die Träger 12 können aus einem Gewebe oder einem Gitter, insbesondere einem Glasfasergewebe oder einem Glasfasergitter hergestellt sein.The carriers 12 can be made from a fabric or a grid, in particular a glass fiber fabric or a glass fiber grid.

Die Beschichtung 14 ist in dieser ersten Ausführungsform vollflächig und auf beiden Seiten der Träger 12 aufgebracht, sodass jeweils der gesamte Träger 12 mit der Beschichtung 14 versehen ist.In this first embodiment, the coating 14 is applied over the entire surface and on both sides of the carrier 12, so that the entire carrier 12 is provided with the coating 14.

Die Träger 12 sind überlappend angeordnet, wobei zwischen zwei Trägern 12 jeweils ein Überlappbereich U entsteht.The carriers 12 are arranged in an overlapping manner, an overlap area U being created between two carriers 12.

Im Überlappbereich U sind die Träger 12 mittels jeweils zwei Klammern 16 aneinander befestigt, wodurch ein langes Band 18 gebildet wird.In the overlap area U, the carriers 12 are fastened to one another by means of two clamps 16, whereby a long band 18 is formed.

Das Band 18 hat eine Längsrichtung L, sodass auch die Träger 12 Längsenden 24, 26 aufweisen.The band 18 has a longitudinal direction L, so that the carriers 12 also have longitudinal ends 24, 26.

Die Klammern 16 sind in Längsrichtung L nur an einer Stelle vorgesehen, das heißt nicht zueinander versetzt. Selbstverständlich kann auch jeweils nur eine Klammer 16 zur Befestigung zweier Träger 12 vorgesehen sein. Die Klammern 16 können auch um 90° gedreht angeordnet sein (nicht gezeigt).The brackets 16 are only provided at one point in the longitudinal direction L, that is, not offset from one another. Of course, only one clamp 16 can be provided for fastening two supports 12. The clamps 16 can also be arranged rotated by 90 ° (not shown).

Denkbar ist auch, dass die Träger 12 durch eine Naht mit einem Faden, aus beispielweise aus Polyamid-, Aramid-, Carbon-, Glas-, Keramik-, oder Stahlfaser, aneinander befestigt sind und/oder dass der erste und der letzte Träger 12 ebenfalls miteinander verbunden sind, sodass ein Ring erhalten wird.It is also conceivable that the carriers 12 are attached to one another by a seam with a thread made, for example, of polyamide, aramid, carbon, glass, ceramic or steel fibers and / or that the first and last carrier 12 are also connected to each other so that a ring is obtained.

Zur besseren Beschreibung wird die rechte Seite in den Figuren als vordere Seite bezeichnet. Selbstverständlich hat ein Band 18 keine solche vorgegebene Richtung, jedoch kann dadurch zwischen dem vorderen Längsende 24 und dem hinteren Längsende 26 der Träger 12 unterschieden werden. Auch werden die Träger 12, die rechts von einem bestimmten Träger angeordnet sind, als "nachfolgende Träger" bezeichnet, und die Träger 12 die links von einem bestimmten Träger 12 angeordnet sind, werden als "vorhergehende Träger" bezeichnet.For a better description, the right side is referred to in the figures as the front side. Of course, a band 18 does not have such a predetermined direction, but a distinction can thereby be made between the front longitudinal end 24 and the rear longitudinal end 26 of the carrier 12. Also, the carriers 12 located to the right of a particular carrier are referred to as "subsequent carriers" and the carriers 12 located to the left of a particular carrier 12 are referred to as "previous carriers".

Die Träger 12 sind identisch ausgeführt und identisch aneinander befestigt, sodass nun beispielhaft der Aufbau des Bandes 18 der Brandschutzvorrichtung 10 mithilfe eines mittleren Trägers 20, d.h. eines Träger 12 in der Mitte des Bandes 18, erläutert wird.The carriers 12 are of identical design and are fastened to one another in an identical manner, so that now, by way of example, the construction of the belt 18 of the fire protection device 10 using a central carrier 20, i. a carrier 12 in the middle of the belt 18 is explained.

In Figur 3a ist der mittlere Träger 20 in Draufsicht dargestellt. Der mittlere Träger 20 sowie alle anderen Träger 12 weisen eine rechteckige Grundfläche auf, wobei die längere Seite 27 in Längsrichtung L des Bandes 18 orientiert ist. Vom vorderen Längsende 24 erstreckt sich in Längsrichtung L ein Einschnitt 28 in Richtung zum hinteren Längsende 26 des mittleren Trägers 20.In Figure 3a the middle carrier 20 is shown in plan view. The middle carrier 20 as well as all other carriers 12 have a rectangular base area, the longer side 27 being oriented in the longitudinal direction L of the band 18. An incision 28 extends from the front longitudinal end 24 in the longitudinal direction L in the direction of the rear longitudinal end 26 of the central support 20.

Denkbar ist auch, wie in Figur 3b dargestellt, dass die Träger 12 mehrere Einschnitte 28, hier zwei Einschnitte 28 aufweisen.It is also conceivable, as in Figure 3b shown that the carriers 12 have several incisions 28, here two incisions 28.

Wie in den Figuren 1 und 2 zu erkennen, hat der mittlere Träger 20 einen benachbarten vorhergehenden Träger 30 und einen benachbarten nachfolgenden Träger 32, sodass der mittlere Träger 20 in zwei Überlappbereichen U liegt, nämlich in einem Überlappbereich mit dem vorhergehenden Träger 30 und einem Überlappbereich mit dem nachfolgenden Träger 32.As in the Figures 1 and 2 As can be seen, the middle carrier 20 has an adjacent preceding carrier 30 and an adjacent subsequent carrier 32, so that the central carrier 20 lies in two overlapping areas U, namely in an overlapping area with the preceding carrier 30 and an overlapping area with the following carrier 32.

Der mittlere Träger 20 ist an seinem hinteren Längsende 26 mit dem vorhergehenden Träger 30 durch die Klammern 16 verbunden.The middle carrier 20 is connected at its rear longitudinal end 26 to the preceding carrier 30 by the clips 16.

Auf gleiche Weise ist der mittlere Träger 20 mit seinem nachfolgenden Träger 32 verbunden, wobei hier die Klammern 16 am hinteren Längsende des nachfolgenden Trägers 32 und damit mittig im mittleren Träger 20 vorgesehen sind. Auf diese Weise unterteilen die Klammern 16 bzw. die Verbindung der Träger 20, 32 den mittleren Träger 20 in zwei Abschnitte.In the same way, the middle carrier 20 is connected to its subsequent carrier 32, the clips 16 being provided here at the rear longitudinal end of the subsequent carrier 32 and thus in the middle in the central carrier 20. In this way, the brackets 16 or the connection between the carriers 20, 32 divide the central carrier 20 into two sections.

Dabei ist der vordere Abschnitt inklusive dem vorderen Längsende 24 unbefestigt, wohingegen der hintere Abschnitt mit dem vorhergehenden Träger 30 verbunden ist.The front section including the front longitudinal end 24 is unattached, whereas the rear section is connected to the preceding carrier 30.

Der Einschnitt 28 des mittleren Trägers 20 erstreckt sich nahezu vollständig durch den vorderen Abschnitt des mittleren Trägers 20.The incision 28 of the central beam 20 extends almost completely through the front portion of the central beam 20.

In Figur 4 ist die Brandschutzvorrichtung 10 ohne Belastung ausgebreitet dargestellt. Hier ist zu erkennen, dass die Träger 12 konkav ausgeführt sein können, sodass die vorderen Längsenden 24 beziehungsweise die vorderen Abschnitte von den nachfolgenden Trägern 32 beabstandet sind.In Figure 4 the fire protection device 10 is shown spread out without loading. It can be seen here that the supports 12 are concave can, so that the front longitudinal ends 24 or the front sections are spaced from the following carriers 32.

Dadurch, dass die Beschichtung 14 vollflächig auf die Träger 12 aufgebracht ist, ist die Beschichtung 14 in jedem der Überlappbereiche U und auch im Bereich des vorderen Längsendes 26 zwischen den überlappenden Trägern 32 und 20 vorgesehen.Because the coating 14 is applied over the entire surface of the carrier 12, the coating 14 is provided in each of the overlapping areas U and also in the area of the front longitudinal end 26 between the overlapping carriers 32 and 20.

In den Figuren 5a und 5b ist ein Durchbruch 34 in einer Wand 36 dargestellt, durch den eine Leitung 38 verläuft.In the Figures 5a and 5b an opening 34 is shown in a wall 36 through which a line 38 extends.

Die Leitung 38 füllt den Durchbruch 34 jedoch nicht vollständig aus, sodass zwischen der Leitung 38 und einer Innenwand 40 des Durchbruches 34 ein Spalt entsteht. In diesem Spalt ist die Brandschutzvorrichtung 10 angeordnet. Aus Gründen der Übersichtlichkeit sind in den Figuren 5a und 5b nur die Träger 12 der Brandschutzvorrichtung 10 und nicht auch noch die Beschichtung 14 dargestellt.However, the line 38 does not completely fill the opening 34, so that a gap is created between the line 38 and an inner wall 40 of the opening 34. The fire protection device 10 is arranged in this gap. For the sake of clarity, the Figures 5a and 5b only the carrier 12 of the fire protection device 10 and not also the coating 14 is shown.

Das Band 18 der Brandschutzvorrichtung 10 umgibt die Leitung 38 vollständig, sodass das Band 18 einen Ring beschreibt.The band 18 of the fire protection device 10 completely surrounds the line 38 so that the band 18 describes a ring.

Die Brandschutzvorrichtung 10 ist derart in den Spalt eingelegt, dass die freien, vorderen Längsenden 24 der Träger 12 radial innen liegen. Das bedeutet, dass die im jeweiligen Überlappbereich U radial innen liegenden Träger 12 gegenüber den jeweiligen radial außen liegenden Trägern 12 beweglich sind.The fire protection device 10 is inserted into the gap in such a way that the free, front longitudinal ends 24 of the supports 12 lie radially inward. This means that the beams 12 lying radially on the inside in the respective overlap region U are movable with respect to the respective beams 12 lying radially on the outside.

Ebenso sind durch diese Anordnung die Längsenden der Träger 12, die im Überlappbereich U radial außen liegen, am radial innen liegenden Träger 12 mit den Klammern 16 befestigt.This arrangement also means that the longitudinal ends of the supports 12, which lie radially outside in the overlap region U, are fastened to the radially inside support 12 with the clips 16.

Die freien, vorderen Längsenden 24 sind dabei aufgrund der konvexen Form der Träger 12 gegen die Leitungen 38 vorgespannt.The free, front longitudinal ends 24 are biased against the lines 38 due to the convex shape of the carrier 12.

Im Falle eines Feuers im Bereich des Durchbruches 34 schmilzt zunächst die Leitung 38 und hinterlässt an dieser Stelle einen Hohlraum im Durchbruch 34, der vollständig von der Brandschutzvorrichtung 10 umgeben ist.In the event of a fire in the area of the opening 34, the line 38 first melts and leaves a cavity in the opening 34 at this point, which is completely surrounded by the fire protection device 10.

Die vorderen Längsenden 24 der Träger 12 bewegen sich, sobald die Leitung 38 zerstört wurde, aufgrund ihrer Vorspannung radial nach innen. Auf diese Weise wird die Oberfläche, die mit dem durch den Hohlraum ziehenden heißen Rauch oder mit dem Feuer in Berührung kommt, vergrößert, da nun Abstände bzw. Kanäle zwischen den einzelnen Trägern 12 entstanden sind.The front longitudinal ends 24 of the carrier 12 move, as soon as the line 38 has been destroyed, due to their prestressing radially inward. To this In this way, the surface area that comes into contact with the hot smoke moving through the cavity or with the fire is enlarged, since gaps or channels between the individual supports 12 are now created.

Erhitzen sich nun Bereiche der Beschichtung 14 soweit, dass die Intumeszenz einsetzt, so bläht die Beschichtung 14 in diesen Bereichen auf. Dabei drückt sie die freien, vorderen Längsenden 24 der Träger 12 in diesem Bereich weiter in den Hohlraum hinein und vergrößert dadurch den Abstand und die Kanäle zwischen den einzelnen Trägern 12 weiter.If areas of the coating 14 are now heated to such an extent that intumescence begins, the coating 14 expands in these areas. In doing so, it presses the free, front longitudinal ends 24 of the supports 12 in this area further into the cavity and thereby further increases the distance and the channels between the individual supports 12.

Auf diese Weise wird die Oberfläche der Brandschutzvorrichtung 10 und damit die Strömung von heißem Rauch oder Feuer durch die Brandschutzvorrichtung 10 weiter vergrößert.In this way, the surface of the fire protection device 10 and thus the flow of hot smoke or fire through the fire protection device 10 is further enlarged.

Somit isolieren bereits aufgeblähte Bereiche der Beschichtung 14 nicht die übrigen, inaktiven Bereiche. Vielmehr ist das Gegenteil der Fall, da Bereiche, die bereits aufgebläht sind, zu einer Vergrößerung der Abstände und Kanäle führen und somit einen besseren Wärmetransport zu den inaktiven Bereichen ermöglichen. Dieser Effekt verstärkt sich selbst, bis schließlich die gesamte Beschichtung 14 aufgebläht ist.Thus, areas of the coating 14 that have already been inflated do not isolate the remaining, inactive areas. Rather, the opposite is the case, since areas that are already inflated lead to an increase in the distances and channels and thus enable better heat transport to the inactive areas. This effect intensifies itself until finally the entire coating 14 is inflated.

Wenn die gesamte Beschichtung 14 aufgebläht ist, sind alle freien Längsenden 24 der Träger 12 zur Mitte hin bewegt worden und die in Figur 5b dargestellte, blendenartige Struktur der Brandschutzvorrichtung 10 ist entstanden. Diese stellt die Volumenoptimale Verteilung der Ausgangsmasse dar.When all of the coating 14 is inflated, all of the free longitudinal ends 24 of the carriers 12 have been moved towards the center and shown in FIG Figure 5b The diaphragm-like structure of the fire protection device 10 shown has arisen. This represents the volume-optimal distribution of the starting material.

In dieser Situation ist der gesamte Hohlraum bzw. der gesamte Durchbruch 34 durch die intumeszierte Beschichtung 14 ausgefüllt, sodass der Durchbruch 34 wieder rauch- und feuerfest verschlossen ist. Die Aschekrustenstabilität wird durch den Träger verstärkt.In this situation, the entire cavity or the entire opening 34 is filled by the intumescent coating 14, so that the opening 34 is closed again in a smoke and fire-proof manner. The ash crust stability is enhanced by the carrier.

In Figur 6 ist eine zweite Ausführungsform der Brandschutzvorrichtung 10 dargestellt. Sie entspricht im Wesentlichen der ersten Ausführungsform der Brandschutzvorrichtung nach Figur 1, sodass im Folgenden nur auf die Unterschiede eingegangen wird. Gleiche und funktionsgleiche Teile sind mit denselben Bezugszeichen versehen.In Figure 6 a second embodiment of the fire protection device 10 is shown. It essentially corresponds to the first embodiment of the fire protection device Figure 1 , so that only the differences are discussed below. Identical and functionally identical parts are provided with the same reference symbols.

Ein Unterschied zur ersten Ausführungsform liegt darin, dass die Beschichtung 14 nur einseitig auf den Trägern 12 aufgebracht ist.A difference from the first embodiment is that the coating 14 is only applied to one side of the carrier 12.

Die Beschichtung 14 ist an der Seite auf den Trägern 12 aufgebracht, die im befestigten Zustand der Brandschutzvorrichtung 10 im Durchbruch 34 radial innen liegt.The coating 14 is applied to the side of the carrier 12 which, when the fire protection device 10 is fastened, lies radially on the inside in the opening 34.

Ein zweiter Unterschied besteht darin, dass das freie Ende (ca. 60%) länger ist und somit größere Durchmesser abgedeckt werden können. Vorzugsweise weist die Brandschutzvorrichtung 10 im Überlappbereich U einen Träger mit 3 Lagen auf.A second difference is that the free end (approx. 60%) is longer and therefore larger diameters can be covered. The fire protection device 10 preferably has a support with 3 layers in the overlap region U.

In Figur 7 ist eine weitere Ausführungsform der Brandschutzvorrichtung 10 an einer Wand 36 befestigt dargestellt.In Figure 7 a further embodiment of the fire protection device 10 is shown attached to a wall 36.

In dieser Ausführungsform sind Haken 44 am Band 18, also an einzelne Trägern 12, vorgesehen, mit denen die Brandschutzvorrichtung 10 an der Wand 36 befestigt ist. Durch diese Art der Anbringung ist es möglich, den Durchmesser des Durchbruches 34 zu kleiner zu wählen. Die Haken 44 können aus Stahl sein.In this embodiment, hooks 44 are provided on the belt 18, that is to say on individual carriers 12, with which the fire protection device 10 is fastened to the wall 36. This type of attachment makes it possible to select the diameter of the opening 34 to be too small. The hooks 44 can be made of steel.

Die Brandschutzvorrichtung 10 selbst kann dabei ansonsten gemäß einer der vorhergehenden Ausführungsformen ausbildet sein.The fire protection device 10 itself can otherwise be designed according to one of the preceding embodiments.
